-      whether to show any "Add <EngineName>" menu items in the drop-down.

-               This has a couple of effects, depending on whether there is

-               (1) If true and the last one-off is currently selected,

-               this method to return true.  Calling advanceSelection again after

-               Likewise if decrementing the index when the first one-off is
-               selected, except in the opposite direction of course.
-               (2) If true and there currently is no selection, decrementing the
-               index will cause the last one-off to become selected and this
-               method to return true.  Only the aForward=false case is affected
-               because it is always the case that if aForward=true and there
-               currently is no selection, the first one-off becomes selected and
-               this method returns true.
-        @param aCycleEngines
-               If true, only engine buttons are included.

-               The number of items in the list.  The reason that this is a

-               When the last list item is selected and the user presses Down,
